Looks like Fall 2011. Interesting, in that this is from Sony and not Sony Erricson.

Quote:

The first is the 9.4-inch S1 media tablet (aka, Qriocity focus) with a curved top much like a folded magazine and both front- and rear-facing cameras. The S1 features a Tegra 2 SoC and "Quick and Smooth" touch panel UI with "Swift" web browser. It can also be used as a remote control for Sony gear. Oh, and both tablets are PlayStation Certified.

The second is the dual-screen S2 clamshell with its pair of 5.5-inch 1,024 x 480 pixel displays, Tegra 2 SoC, and cameras.
